What is Diffuse Idiopathic Skeletal Hyperostosis (DISH)?

Diffuse idiopathic skeletal hyperostosis (DISH) is a condition that causes bone to form in abnormal places. DISH most commonly affects the mid back (thoracic spine) but may also affect the neck (cervical spine), low back (lumbar spine), hips, heels, and other areas. DISH is also known as Forestier's disease, spondylitis ossificans ligamentosa, spondylosis hyperostotica, and ankylosing hyperostosis of the spine. The exact cause of DISH is not known. DISH is more common in men than women and the elderly. DISH is uncommon before age 40. Decreased range of motion of the spine, especially in the mid back, is the most common sign of DISH. The diagnosis of DISH is made using X-rays. The treatment of DISH involves treating each bothersome symptom, if there are any.
